Objectives: Characterize a cohort of patients with breast cancer diagnosed by stereotaxic guidance, and confirmed by pathology. Describe the benefits of the method from the safety and ambulatory point of view, diagnostic help and guidance for the oncologist surgeon. Materials and methods: Descriptive observational study of a retrospective cohort. We reviewed all the records of patients who attended for suspected of breast lesions who underwent a biopsy guided by stereotaxis (BGS) in the period between May 2016 and December 2017, with standard mammography technique. The distribution of the quantitative variables was evaluated with the Kolmogorov-Smirnov test. Exploratory crosses were made between the findings of the BGS and the pathological diagnosis with the Chi-square test; for the comparison of quantitative variables following a nonparametric distribution the Mann Whitney U test was used. Results: We included 36 women with a median age of 56.5 years, the total of the sample had a radiological classification pre-biopsy BIRADS 4b (27.8%), followed by BIRADS 3 (25%). The most frequent lesions described in the BGS were microcalcifications (55.6%). The pathology was carcinoma in situ in 47.2%. No significant differences were found in the age distribution by pathology (p = 0.109). Conclusions: Stereotactic-guided breast biopsy is a safe and reliable method for the diagnosis of patients with breast cancer, with an excellent correlation between the findings according to the BIRADS category and the pathology, as a guide for therapeutic intervention by the oncologist surgeon.
